<p>PROBLEM TO BE SOLVED: To provide a small-sized, less-expensive, easy-manufactured and simply installed exhaust acceleration device that can be directly post-fitted to an existing facility whatever internal combustion engines and external combustion engines may be applied.SOLUTION: An exhaust outer cylinder 1 and an inner cylinder 2 having a plurality of exhaust through-holes 2A at its outer surface side with a shape of funnel-like circular truncated cone or truncated pyramid so as to communicate with an inner surface side are installed at an arbitrary position in a line ranging from an exhaust port of a heat engine to a terminal end of an exhaust pipe; the inner cylinder 2 having a larger sectional area is applied as an exhaust inlet port 2C toward an upstream side; the inner cylinder 2 having a smaller sectional area is applied as an exhaust injection port toward a downstream side; a plurality of mounting plates 4 having a prescribed angle crossed at a right angle in parallel with a flow of exhaust gas are installed; and each of the inner members of the exhaust outer cylinder 1 is connected and fixed to generate a circulating flow in the exhaust flow.</p> |
